{"id":"UBUNTU-CVE-2025-43718","details":"Poppler 24.06.1 through 25.x before 25.04.0 allows stack consumption and a SIGSEGV via deeply nested structures within the metadata (such as GTS_PDFEVersion) of a PDF document, e.g., a regular expression for a long pdfsubver string. This occurs in Dict::lookup, Catalog::getMetadata, and associated functions in PDFDoc, with deep recursion in the regex executor (std::__detail::_Executor).","modified":"2026-04-27T19:08:28.773011Z","published":"2025-10-02T00:00:00Z","related":["USN-7803-1"],"upstream":["CVE-2025-43718"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-43718"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-43718"},{"type":"REPORT","url":"https://github.com/ShadowByte1/CVE-Reports/blob/main/CVE-2025-43718.md"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7803-1"}],"affected":[{"package":{"name":"poppler","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/poppler@0.41.0-0ubuntu1.16+esm8?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.33.0-0ubuntu3","0.37.0-0ubuntu1","0.38.0-0ubuntu1","0.41.0-0ubuntu1","0.41.0-0ubuntu1.1","0.41.0-0ubuntu1.2","0.41.0-0ubuntu1.3","0.41.0-0ubuntu1.4","0.41.0-0ubuntu1.5","0.41.0-0ubuntu1.6","0.41.0-0ubuntu1.7","0.41.0-0ubuntu1.8","0.41.0-0ubuntu1.9","0.41.0-0ubuntu1.10","0.41.0-0ubuntu1.11","0.41.0-0ubuntu1.12","0.41.0-0ubuntu1.13","0.41.0-0ubuntu1.14","0.41.0-0ubuntu1.15","0.41.0-0ubuntu1.16","0.41.0-0ubuntu1.16+esm1","0.41.0-0ubuntu1.16+esm2","0.41.0-0ubuntu1.16+esm3","0.41.0-0ubuntu1.16+esm4","0.41.0-0ubuntu1.16+esm5","0.41.0-0ubuntu1.16+esm6","0.41.0-0ubuntu1.16+esm7","0.41.0-0ubuntu1.16+esm8"],"ecosystem_specific":{"binaries":[{"binary_version":"0.41.0-0ubuntu1.16+esm8","binary_name":"gir1.2-poppler-0.18"},{"binary_version":"0.41.0-0ubuntu1.16+esm8","binary_name":"libpoppler-cpp0"},{"binary_version":"0.41.0-0ubuntu1.16+esm8","binary_name":"libpoppler-glib8"},{"binary_version":"0.41.0-0ubuntu1.16+esm8","binary_name":"libpoppler-qt4-4"},{"binary_version":"0.41.0-0ubuntu1.16+esm8","binary_name":"libpoppler-qt5-1"},{"binary_version":"0.41.0-0ubuntu1.16+esm8","binary_name":"libpoppler58"},{"binary_version":"0.41.0-0ubuntu1.16+esm8","binary_name":"poppler-utils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-43718.json"}},{"package":{"name":"poppler","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/poppler@0.62.0-2ubuntu2.14+esm8?arch=source&distro=esm-infra/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.57.0-2ubuntu4","0.57.0-2ubuntu5","0.62.0-1ubuntu1","0.62.0-2ubuntu1","0.62.0-2ubuntu2","0.62.0-2ubuntu2.1","0.62.0-2ubuntu2.2","0.62.0-2ubuntu2.4","0.62.0-2ubuntu2.5","0.62.0-2ubuntu2.6","0.62.0-2ubuntu2.7","0.62.0-2ubuntu2.8","0.62.0-2ubuntu2.9","0.62.0-2ubuntu2.10","0.62.0-2ubuntu2.11","0.62.0-2ubuntu2.12","0.62.0-2ubuntu2.13","0.62.0-2ubuntu2.14","0.62.0-2ubuntu2.14+esm1","0.62.0-2ubuntu2.14+esm2","0.62.0-2ubuntu2.14+esm3","0.62.0-2ubuntu2.14+esm4","0.62.0-2ubuntu2.14+esm5","0.62.0-2ubuntu2.14+esm6","0.62.0-2ubuntu2.14+esm7","0.62.0-2ubuntu2.14+esm8"],"ecosystem_specific":{"binaries":[{"binary_version":"0.62.0-2ubuntu2.14+esm8","binary_name":"gir1.2-poppler-0.18"},{"binary_version":"0.62.0-2ubuntu2.14+esm8","binary_name":"libpoppler-cpp0v5"},{"binary_version":"0.62.0-2ubuntu2.14+esm8","binary_name":"libpoppler-glib8"},{"binary_version":"0.62.0-2ubuntu2.14+esm8","binary_name":"libpoppler-qt5-1"},{"binary_version":"0.62.0-2ubuntu2.14+esm8","binary_name":"libpoppler73"},{"binary_version":"0.62.0-2ubuntu2.14+esm8","binary_name":"poppler-utils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-43718.json"}},{"package":{"name":"poppler","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/poppler@0.86.1-0ubuntu1.7+esm3?arch=source&distro=esm-infra/focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.80.0-0ubuntu1","0.80.0-0ubuntu3","0.80.0-0ubuntu4","0.80.0-0ubuntu5","0.85.0-1ubuntu1","0.85.0-1ubuntu3","0.86.1-0ubuntu1","0.86.1-0ubuntu1.1","0.86.1-0ubuntu1.2","0.86.1-0ubuntu1.3","0.86.1-0ubuntu1.4","0.86.1-0ubuntu1.5","0.86.1-0ubuntu1.6","0.86.1-0ubuntu1.7","0.86.1-0ubuntu1.7+esm1","0.86.1-0ubuntu1.7+esm2","0.86.1-0ubuntu1.7+esm3"],"ecosystem_specific":{"binaries":[{"binary_version":"0.86.1-0ubuntu1.7+esm3","binary_name":"gir1.2-poppler-0.18"},{"binary_version":"0.86.1-0ubuntu1.7+esm3","binary_name":"libpoppler-cpp0v5"},{"binary_version":"0.86.1-0ubuntu1.7+esm3","binary_name":"libpoppler-glib8"},{"binary_version":"0.86.1-0ubuntu1.7+esm3","binary_name":"libpoppler-qt5-1"},{"binary_version":"0.86.1-0ubuntu1.7+esm3","binary_name":"libpoppler97"},{"binary_version":"0.86.1-0ubuntu1.7+esm3","binary_name":"poppler-utils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-43718.json"}},{"package":{"name":"poppler","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/poppler@22.02.0-2ubuntu0.11?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"22.02.0-2ubuntu0.11"}]}],"versions":["21.06.1-1","21.11.0-1~ubuntu2","22.02.0-2","22.02.0-2ubuntu0.1",
